Concept explainers
In a certain code language, numerals are each represented by a symbol or a letter.
They are as follows
Numerals are to be coded as per the codes in the table and the following conditions:
a. If the first and the last digits are odd, both are to be coded as 'X'.
b. If the first and the last digits are even, both are to be coded as
c. If the last digit is '0', it is to be coded as
For example, 487692 is coded as

- Serendipity Booksellers has a book club that awards points to its customers based on the number of books purchased each month. The points are awarded as follows: If a customer purchases no books, he or she earns 0 points If a customer purchases 1 through 5 books, he or she earns 5 points for each book. If a customer purchases 6 through 10 books, he or she earns 10 points for each book. If a customer purchases 11 or more books, he or she earns points equal to 20 points for each book. (Use Python) Use the Design Recipe to write the function customer_rewards which consumes the number of books purchased, and returns the total points. Include a docstring! Write 3 assert_equal statements to test your function.arrow_forwardCompute the income tax due on taxable income entered by the user, given the data as shown in the following table. Be sure to include error checking to make sure the user does not enter a negative number. Assume all entries are integer values.

- Primary U.S. interstate highways are numbered 1-99. Odd numbers (like the 5 or 95) go north/south, and evens (like the 10 or 90) go east/west. Auxiliary highways are numbered 100-999 and service the primary highway indicated by the rightmost two digits. Thus, the 405 services the 5, and the 290 services the 90. Given a highway number, indicate whether it is a primary or auxiliary highway. If auxiliary, indicate what primary highway it serves. Also, indicate if the (primary) highway runs north/south or east/west. Ex: If the input is: 90 The output is: The 90 is primary, going east/west. Ex: If the input is: 290 The output is: The 290 is auxiliary, serving the 90, going east/west. Ex: If the input is: 0 Or any number not between 1 and 999, the output is: 0 is not a valid interstate highway number. import java.util.Scanner; public class LabProgram { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); int highwayNumber; int…arrow_forwardC Code The salary of a company is paid according to working hours: Within 4 hours, including 4 hours, the salary is 50 yuan. The time is between 4 and 8 hours. On the basis of 50 yuan for 4 hours, the time over 4 hours will be charged at 20 yuan per hour. If the time exceeds 8 hours, on the basis of the wage of the first 8 hours, the extra time will be calculated at 30 yuan per hour. Enter working hours and calculate wages.

Using the above formula write a program that will display the following table.

- One Computer Science program uses the following rules for CS course placement: 1. if the CS AP score is 4 or higher, a student is placed to CS 221, 2. If the CS AP score is less than 4 (0 means no AP) and the ACT math is 24 or higher, a studenet is placed to CS 180, 3. If the CS AP score is less than 4 and the ACT math is lower than 24, a student is placed to CS 170. Write a java program that can print the appropriate courses for each of three cases. A sample output is the following 525 CS221 325 CS180 0 20 CS170 where the first and second colomn are the socre of the AP couse and ACT math, respectively. You must use if-else statement in the code since there exists logical relations between the three cases For example, case 2 and case 3 are both "else" cases with respect to case 1 Remember to comment your code, and follow the Java naming convention.arrow_forwardTrue or False 4.

To register as an elector, one must be a Malaysian citizen and be 21 years old and above. Firstly, the user need to key in IC number. If the IC number is not valid, the system will print "IC number is not valid" and quit from the system. If the IC number is valid, the system will then check the age of voters based on the year of birth from the IC number. If the age is 21 and above, the program will print a status as "Qualified". If not, the program will print "Disqualified".
